Fix mistakes in definition of QCA vendor commands for indoor location

Fix some mistakes in the previous commit for adding QCA vendor commands
for indoor location.

Note: The renamed enum value does not change the ABI, but the addition
of QCA_WLAN_VENDOR_ATTR_FTM_MEAS_INVALID in the beginning of enum
qca_wlan_vendor_attr_ftm_meas does renumber
QCA_WLAN_VENDOR_ATTR_FTM_MEAS_* values. The previous values were
committed yesterday and have not been used in any released code yet, so
this is a justifiable quick fix.
